HIV Comorbidities-Pay Attention to Hypertension Amid Changing Guidelines: An Analysis of Texas Medical Monitoring Project Data

Abstract

Background: Hypertension is a significant risk factor for cardiovascular disease, a leading cause of death among people living with HIV (PLWH). Studies suggest that hypertension prevalence among PLWH is high, yet none assess how the 2017 redefinition of hypertension as ≥130/80 rather than the previous standard of ≥140/90 mm Hg will affect prevalence among PLWH. This study addresses this gap.

Methods: We examined medical record abstractions of 957 PLWH in Texas from the 2013-2014 Medical Monitoring Project survey. Participants with hypertension were identified by charted diagnosis, antihypertensive medication use, or blood pressure readings ≥140/90 and ≥130/80 mm Hg. Associations with sociodemographic and clinical variables were assessed using Rao-Scott chi-square tests, and odds of having hypertension were calculated using multivariable logistic regression models while adjusting for several demographic and HIV-related variables.

Results: The 2017 redefinition of hypertension increased prevalence in the sample by 44.3%, from 47.6% to 68.7%. Age group, body mass index, sex, and race remained significantly associated with hypertension (all P < 0.01). Although prevalence was near equal between males and females at ≥140/90 mm Hg (47.4% and 48.5%, respectively), males were 2.36 times more likely to have hypertension than females (95% confidence interval [CI]: 1.55-3.60) at ≥130/80 mm Hg. Prevalence remained comparable between white (73.3%) and black participants (72.9%).

Conclusions: This study shows that hypertension prevalence is remarkably high among PLWH and is further increased by updated guidelines. Barriers to hypertension control in the HIV care setting should be identified and addressed to facilitate continued improvement in the quality and length of life for PLWH.
